The solution is simple (in the UK), add CCS to all the superchargers, give users an option of £10 per 30 minutes usage, or pay the current lifetime prepayment. As Ecotricity charges £6 for 30 minutes usage (50KW), very few none Tesla owners will choose to pay more for the super charger unless there is no other option nearby.
Remember the Model 3 will most likely be brought by people that don’t drive a long way often, so they would benefit from a per usage charge.
By making the charge time based, Tesla owners get more power for their money….
There is nothing stopping Tesla putting more power var the CCS plug once the software in the car and the charger agree they can both use the “Tesla mode”. The standard even allows for this type of thing, all chargers and car just have to ALSO support the standard mode of operation.
PS in the long term CCS charges can be used for buses etc, as the pins can cope with a MUCH higher power then the Tesla plug, it just needs the chargers to catch up with what the standard allows. CCS is a much better design for the next 30 years……
(More Tesla will be sold in the next 2 year than in the complete history of the company, more none Tesla EV will be sold per year then Tesla cars. So don’t let history restrict the mass-market.)
